Array pointer to numbers in C#

Question

This may sound strange, but can users assign an array pointer to a number; mainly an integer;

If it can be, then would users provide me some examples?

For example:

arr[0]=45;
arr[1]=18;
arr[2]=7;
arr[3]=60;
arr[4]=61;
arr[5]=10;
arr[6]=3;
arr[7]=1;

The random order would be like this:

=randombetween(arr[0]; arr[7]);

1 2 3 4 5
arr[3], arr[0], arr[2], arr[7], arr[4]

Users select 5 out of 7 array pointers:

It seems that using the ref keyword can be done, creating references to references.

But according to your description, I feel that using Dictionary<TKey,TValue> Class may be more suitable for your current situation.

            Dictionary<int, int> keyValuePairs = new Dictionary<int, int>();  
            Dictionary<int, int> dict = new Dictionary<int, int>();  
            keyValuePairs.Add(0,45);  
            keyValuePairs.Add(1,18);  
            keyValuePairs.Add(2,7);  
            keyValuePairs.Add(3,60);  
            keyValuePairs.Add(4,61);  
            keyValuePairs.Add(5,10);  
            keyValuePairs.Add(6,3);  
            keyValuePairs.Add(7,1);  
  
            Random random = new Random();  
            for (int i = 0; i < 5; i++)  
            {  
                var keyValuePair = keyValuePairs.ElementAt(random.Next(0, keyValuePairs.Count));  
                //To avoid selecting the same element repeatedly.  
                keyValuePairs.Remove(keyValuePair.Key);  
                dict.Add(keyValuePair.Key, keyValuePair.Value);  
            }

You can make a program do anything that is applicable to making your solution/program work.

If you want user input to assign a number to an array based on integer elements and assigning a value using an index pointer to the array element in the array, you can do that.

For some random order solution, you are going to have to figure that out, by using a flow chart algorithm or something before you code it. :)
